We’ve all heard a car or truck in our neighborhoods that needs a new muffler. But there’s more to the exhaust system than just the muffler.

The exhaust system has three main functions:

  • To safely get hot exhaust gas from the engine out the tailpipe
  • Treats the exhaust to remove harmful pollutants
  • Muffle the engine noise

To accomplish these goals vehicle manufactures designed an entire system to address the issues. This system is comprised of 3 main components.

  1.  Mufflers
  2. Catalytic Converters
  3. Exhaust Pipe

The exhaust system is attached to the car by a series of hangers and clamps that hold the system in place. And when these hangers come loose or break then hot exhaust components can touch and melt wires, hoses and lines. Just think of how detrimental a hot curling iron can be – but worse. It’s not good to have that waving around.

Catalytic converters are positioned closest to the engine attached by piping from the block down and back towards the muffler. And finally, we end at the tailpipe. Appropriate name. This is the final outlet for the exhaust. And one other component is the oxygen sensor. It monitors the oxygen content of the exhaust so the engine-control computer can adjust the vital fuel-to-air mix to keep the car running right.
